They found the larger fish culled were mostly,if not all males, which changes the ratio of male/female in the 10% cull group, and indicated to me that females CNBG do not grow as fast as the males. I think I want to keep a high % male CNBG in my pond to get the trophy size. Did I get it wrong?
Nope, you got it right. Having a larger % of Males also reduces the number of YOY produced yearly.
